Understand the result
Separate cash fees from your time
Monthly model = sending fees + attachment data
+ setup hours × hourly value / months
+ monthly operating hours × hourly valueTime valuation is an assumption, not a charge from your provider. Keep the two visible when comparing a managed plan with a service that requires more setup work. Provider tiers and prices should be rechecked before purchase.
Make a comparison you can review
Count recipient copies rather than API calls, enter your actual attachment assumptions and edit the displayed prices to match a current quote. Export the scenario so someone else can inspect the inputs; do not present it as a prediction of deliverability.
What this tool can and cannot tell you
Compare the exact plan you can buy. Count recipient deliveries rather than API calls. The time column is your own estimate, not a provider fee. Change the editable tariff inputs to match your quote; this worksheet does not measure deliverability.
Common questions
Why does the tool show provider fees and time separately?
Only the provider-fee column estimates an external bill. Time cost is an internal planning assumption supplied by you.
Can I use a different quote?
Yes. Edit the rate and base-price inputs to match the option you can actually purchase, then rerun the calculation.
Does this compare inbox placement?
No. It budgets volume, data and time. Deliverability requires separate evidence from your sending context.
